COMBINED AIR AND WATER PUMP.

SPECIFICATION forming part of Letters Patent No. 701,163, dated May 2'7, 1902. Application filed February 23, 1901. Serial No. 48,466. (No model.)

To all wiz/0m zit may con/cern:

Be it known that I, EDWARD D. DEETER, a citizen of the United States, and a resident of Milford, in the county of Kosciusko and State of Indiana, have invented a new and Improved Combined Air and Water Pump, of which the following is a full, clear, and exact description.

This invention relates to means for aording a water-supply for buildings not connected with a general water-distributing system such as is provided fora town or city, and usually consisting of a water tank and pump, the tank being attached to the water-distributing service pipe or pipes in the building.

One object of my invention is to provide a pump of novel simple construction adapted for elevating water from a deep or shallow well and forcing the liquid as it is pumped into a sealed tank against the air confined therein, so that pressure of the air will force the water from the tank into a system of water-distributing pipes extending into one or more buildings.

Another objectis to so construct the improved pump that it is adapted to pump air with the water into the receiving-tank, and thus maintain a suitable pressure on the water therein for the adequate supply of water to and through a system of'servicepipes, which may extend throughout a building or block of buildings above the tank; and a further object is to provide novel details of construction for the air-pumping mechanism, which permit adjustment of the same forexact graduation of the amount of air pumped or an arrest of the air-pumping operation, as may be found necessary for efficient service of the improved pneumatic enforced watersupplying apparatus.

The invention consists in the novel construction and combination of parts, as is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a broken and partly-sectional side elevation of the improved air and water pump. Fig. l is a detached side View of a presser-block that is a novel detail of construction employed. Fig. 3 is a detached side viewV of duplicate spring clamping-arms, which receive pressure of the block shown in Fig. 2; and Fig. i is a broken front elevation of a building, a water-holding tank at the base of the building, a Supply-pipe for air and water leading from the improved air and water pump into said tank, and a system of water-distributin g pipes leading upwardly in the building.

The improvements may be applied to pump water from a deep tubular well, a shallow walled well of great-er diameter than a tubular well, or from any other sufficient watersupply.

In the drawings, which show the construction and application of the invention, 4: indicates the lift-pipe of the pump, that is shown broken away intermediately of its ends,

but which in completed condition may have such a length as will permit the lower end thereof to be submerged in the water-supply A, as indicated in Fig. 1. Upon the upper end of the lift-pipe 4 the lower head or end wall of the pump-cylinder 5 is secured either by a screwed engagement therewith or by other means, and, as shown, there is an outlet formed in the side wall of the cylinder for an attachment of one end ofthe pipe 6,through which air and Water passing` from the pump is transferred to a water-receiving tank B through the ordinary check-valve 7. A clackvalve 5n is hingedwithin the cylinder 5 upon its lower end wall, so as to rock above the open upper end of the lift-pipe 4 and serve as y I a foot-valve to prevent regurgitation of waert lifted through the pipe into the cylinder.

A hollow plunger-rod 8 extends vertically of a suitable length, a truly cylindrical portion of its body passing through a packingbox 9, that is positioned on the upper end Wall or bonnet of the cylinder 5. Upon the lower end of the hollow plunger-rod 8 au interiorlythreaded socket-piece 10 is screwed, and into a projection of said socket the upper end of a cylindrical valve-chamber 1l is screwed, whereby the short valve chamber is held alined with the plunger-rod.

A circular and cupped packing-ring 12, formed, preferably, of leather, is held upon ICO y the exterior of the cylindrical valve-chamber -5, as follows: A fiat base-plate 13, having a circularedge, a central perforation, and a plurality of orifices a, formed in the base-plate betweenvits edge and the central perforation, is held-upon the lower end of the valve-chamber 11 by the flanged head of the short screwbolt 14, which engages a thread formed to receive it inthe valve-chamber. The diameter of the base-plate 13 nearly equals that of the bore of the cylinder 5, and upon it the cupped packing-ring -12 is seated, having its peripheral flange extended upwardly.

A preferably dished cap-piece 15 is seated within the cupped packing-ring12 and pressed down upon it by adjustment of the socketpiece 10, the concaved wall of the cap-piece havingasuitable number of apertures formed thereinfproducing the arms l).

A disk` valve 16 lof suitable weight is slidably mounted upon the chamber 11 and may have a slightly-yielding facing c secured upon its level lower surface, which is adapted to seat upon the base-plate 13 over the orifices ...fa"therein, a sufficient space being afforded between the uppermost point in the dished cap-piece 15 and the base-plate 13 to permit Athe disk valve 16 to rise a proper distance from said base-plate, and thus allowthe free passage of water through the orifices a and thence through the spaces between the arms b, as vwill be further explained.

' Acentralpassagecislongitudinallyformed in the clamping bolt yor plug 14, and at the upper termination of said passage a preferably coniform valve-'seat isproduced by the cupped counterboring of said passage.

Within the bore of the plunger-rod 8, at or near its lower end, a centrally -apertured guide 17 is secured, comprising a plurality of spaced arms formi-ng a spider, which is adapted to `permit the free passage of water between its arms. Through the central peryfretion of the spider 17 the lower portion of the valve-'stem 18 is downwardly extended, and 'at the lower extremity of said valve-stem a coniform valve e is secured, which may rest upon the coniform seat formed at the upper end of the passage c'. A coiled spring 19 is introduced between the spider 17 and the valve e, encircling the valve-stem 18, said spring being compressed slightly when the valve e is on its seat, and is thus adapted to insure the proper engagement of said valve therewith if from any cause the valve-stem fails to dro-p by its gravity alone.`

On a bracket-block 20, which is secured by any preferred means upon the exterior of the hollow plunger-rod 8 at a suitable distance above the packing-box 9, a horizontal tappetlever 21 is pivoted between its ends, and one portionof said lever, which passesthrough a lslot g in the plunger-rod, is perforated vertivoldoe cally to receive the loosely-fitted upper portion of the valve-stem 18. v'

The upper side of the portion of the tappetlev'er 21, which extends into the hollow plunger-rod 8, lnay with advantage bev slightly convexed for a suitable engagement with a ball-shaped fulcrum-block 22, that is adjustably held above the tappet-lever on the valvestem 18 by a set-screw 8, and it will be seen that the depressionof the inner end of the tappet-arm below a normal position is prevented bythe abutment-screw 7l, that is inserted through a tappet-hole formed` in the side wall of the hollow plunger-rodat a suitable point.

The twin clamping-arms 23 (shown in Figs. 1 and 3) are clamped at their lower ends, s o as to stand erect, by the slotted member 24, that projects outwardly from the bracket-block,'20 A these springs being held in position by the transverseV bolt m, that engages alined perbe held spaced therefrom a proper distance' by a suitable projection'n. On the upper portion of the post 25 a laterally-extended arm 25:L is formed or secured, having an opening o formed vertically in its free end, through A which the hollow plunger-rod 8 loosely passes near its open upper end.

In a perforation formed in the arm 25aL the screw-threaded cylindrical body pcf a presserblock 26 is held adj ustably by the nuts r, that are screwed upon the bodyp at each side of the arm 25a. The depending head portion ofthe presser-block 26 is preferably given a blunt arrow shape and from its relative position is adapted to pass between the twin clampingsprings 23 when they are elevated a proper degree by the upward travel ofthe hollow plunger-rod 8, as will presently be described.

A slightly-resilient pusher-limb 27 is adjustably held on the post 25 by the clampingbox s, which is slidable on the post and carries the limb on its inner side, a set-screwt serving to secure the box at a desiredypoint on the post. has its free lower end curved slightly toward the post, and is thus adapted to impinge upon the outer end of the rockable lever 2l and press it downwardly without objectionable shock,finally sliding therefrom when the tappet-lever is rocked downa proper degree.

The operation of the pump mechanism for lliftingand forcing water and air is as follows:

.Assuming that the hollow plunger-rod 8 has been connected by means (not shown) with a suitable source of power adapted to give it IOO IOS

IIC

The depending 'pusher-limb 27 y proper reciprocating motion, it will be seen that the reciprocatory travel of this rod, if working parts of the pump are yin the relative positions shown in Fig. 1 will cause the main plunger-head having the cupped packingring l2 to draw air and then water up from and through the lift-pipe et rinto the cylinder 5 below said plunger-head, as indicated in Fig. 1. Each downstroke of the main plunger-head will pass first the air from the liftpipe 4 and then water into the portion of the cylinder 5 above the main plunger-head, as the pressure of water that has entered the lower portion of the cylinder through the clack-valve 5L will on a downstroke of the rod 8 close said valve and lift the disk valve 16, so that water will pass through the orifices in the base-plate 13 of the plunger-head past the raised disk valve to be expelled on the next upstroke of the main plunger-head by closure of said disk valve, the water above the plunger-head then passing into the pipe 6, lifting the check-valve 7 and passing therethrough to the receiving-tank B, previously mentioned.

As it is designed to provide for the elevation of water through the service-pipes C to the upper story of a high building, such as D, there must be a sufficient amount of air-pressure produced in the tankB to effect such a result, and to this end the air-pumping mechanism, that is an essential feature of my invention, is caused to coact with thewaterpumping details, as follows: When the hollow plunger-rod 8 is moving upward, at a predetermined point in its stroke the depending spring-limb 27 will contact with the outer end of the tappet-lever 21, pressing it down, and consequently rocking upward the inner end thereof.

The enforced contact of the inner end of the tappet-lever with the fulcrum-block 22 effects the limited elevation of the valve-stem 1S and valve@ thereon, which will open an air-passage through the plug 14C from the open hollow plunger-rod Sinto the cylinder 5 below the main plunger-head.

It will be obvious that as long as the tappet-lever 21 is held in an inclined position by the spring clamping-arms 23 the valve on the stem 1S will remain unseated and air will pass below the upwardly-moving main plunger-head to mingle with the water that is at the same time entering the lower portion of the cylinder 5 from the lift-pipe 4.

The elevation of the plunger-rod S eventually causes the presser-block 26 to have engagement with the clamping-arms 23, spreading them apart and permitting the gravity of the valve-stem 18, supplemented by the tension of the compressed spring 19, to close the valve c upon its seat and arrest the passage of air down through the duct c into the lower portion of the cylinder 5.

Obviously the continuation of the pumping operation will at every reciprocatory movement of the plunger-rod S and main plungerhead thereon pump a quantity of air along with the water into the tank B, and thus produce a proper compression of air over the water therein for the expulsion of the water into and through the system of service-pipes in one or more buildings required to be supplied with a full amount of water in all stories of the building.`

As the spring-limb 27 may be adjusted to occupy any desired position on the post 25, it will be seen that the length of time during each stroke of the pump-plunger in which the valve e :is to remain unseated may be eX- actly determined by the relative position given to said spring-limb, it being apparent that the lower said limb is placed on the post the longer will the valve remain open for induction of air.

If it is at any time desired to discontinue the use of the air-pump, this can be readily effected if the spring-limb 27 is raised to the upper end of the post 25, as then the presserblock 26 will spread apart the clamping-arms 23 for the release of the tappet-lever 21 immediately after the depending limb 27 has depressed the outer end of said lever, so that the valve-stem 18 and valve e thereon will practically remain in lowered condition.

It has been stated that the invention is of a class employed to furnish a water-supply for buildings not connected to a general water-supply. I do not, however, desire to limit the use of the improvement, but may employ itin some situations in connection with ageneral water-supply for the elevation of water to a greater height than the general supply will effect.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
